This shimmering paste has many properties of a shield spell. When you slather it onto a creature or object, the target gains a +1 circumstance bonus to AC for 1 round.
The first time a physical attack or a magic missile hits the target during that round, the oil prevents 5 damage from that attack or spell, and then the oil's effect ends.
Effect: Shielding Salve
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
AbjurationEffects and magic items with this trait are associated with the abjuration school of magic, typically involving protection or wards.
ConsumableAn item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
OilOils are magical gels, ointments, pastes, or salves that are typically applied to an object and are used up in the process.
